A reciprocating piston compressor including at least one cylinder, a reciprocable piston disposed therein, a crankshaft rotatable in forward and reverse directions and having an eccentric crankpin, and a cam disposed about the crankpin, the piston operatively connected to the cam. The cam is rotatable about the crankpin between a first angular position corresponding to a first piston stroke length during forward crankshaft rotation and a second angular position corresponding to a second piston stroke length during reverse crankshaft rotation. In one of its first and second angular positions, the cam is rotatably locked to the crankpin.
